Proof American Gold Eagles

The American Gold Eagle was first issued in 1986, the same year as the Silver Eagle. It is struck in 22-karat gold (.9167 fine) and comes in four denominations:

$50 — One Ounce (most common and most valuable)
$25 — Half Ounce
$10 — Quarter Ounce
$5 — Tenth Ounce

The obverse features Augustus Saint-Gaudens' iconic Lady Liberty striding forward, adapted from the famous 1907 Saint-Gaudens Double Eagle. The reverse features a family of eagles — a male eagle carrying an olive branch flying above a nest where a female eagle sits with hatchlings.

Proof Gold Eagle Varieties

Standard Proof — struck at West Point with a "W" mint mark; issued every year since 1986
Reverse Proof — frosted fields with mirror-finish devices; issued for special anniversary sets
Type 1 vs. Type 2 — in 2021 the reverse design was updated; both types are actively collected
4-Coin Proof Sets — all four denominations in one presentation case; highly sought after by collectors

Proof American Gold Buffalos

The American Gold Buffalo was introduced in 2006 as the first 24-karat (.9999 fine) gold coin ever produced by the U.S. Mint. It features James Earle Fraser's classic Buffalo Nickel design — the same design used on the 1913–1938 five-cent piece — making it one of the most beloved American coin designs ever created.

The Gold Buffalo is issued in a single denomination:

$50 — One Ounce (.9999 fine gold)

2017-W Proof — lower mintage than surrounding years

What Affects the Value of Your Proof Gold Coins?

1. Gold Spot Price All Proof Gold Eagles and Buffalos have a base value tied to the current gold spot price. A one-ounce coin is always worth at least the value of one ounce of gold — often significantly more.

2. Original Packaging Coins in original U.S. Mint presentation boxes with the Certificate of Authenticity are worth more. Never remove coins from their capsules or clean them.

3. Grade Proof coins graded PR70 (perfect) by PCGS or NGC command substantial premiums over PR69 examples. For key dates, the difference can be hundreds or even thousands of dollars.

4. Date and Denomination Key dates and low-mintage issues carry premiums well above gold spot. The 2008 fractional Gold Buffalos in particular are among the most valuable modern U.S. coins.

5. Complete Sets A complete date run of Proof Gold Eagles or Proof Gold Buffalos is worth more as a complete set. We pay strong premiums for complete collections.

Should You Get Your Proof Gold Coins Graded?

For common dates, grading costs may not be justified. But for:

Key dates (2008 fractionals, 1999-W unfinished proof dies, etc.)
Coins you believe are PR70
Complete sets you want to maximize value on

...PCGS, NGC and CACG grading can significantly increase what you receive. We are PCGS, NGC and CACG authorized dealers and can advise you before you spend money on submission fees.
